Tim Peake and space station crew mates return to Earth

The European Space Agency is evaluating three proposals for medium-class missions focused on the entire range of scales in the cosmos, from planetary geology to solar system evolution to gamma ray bursts in the early universe.

The European Space Agency’s Rosetta spacecraft closed in Thursday for a deliberate crash landing on the surface of comet 67P/Churyumov-Gerasimenko on Friday, a slow-motion kamikaze plunge to bring the enormously successful mission to an end after more than two years of unprecedented close-range observations.

Rosetta flight director Andrea Accomazzo tells us in this video interview how the Rosetta spacecraft will make its final plunge towards the surface of Comet 67P/Churyumov–Gerasimenko.
